To aZZ whom it may concern.-

Be" it known that I, NATHL. WV. WEST, a .citizemef the United States,residing at Alna, in the county of Lincoln and State of Maine,

have invented a new and useful Roofing-Clamp,

that class which have for their object to support staging or scaffoldingupon the roofs of houses while repairs are being made to the same; andit relates particularly to a simple and etficient clamp for supportingor hold- :5 ing in position the so-called gutter-hooks,

whereby stagingis secured upon the gable end of buildings.

My invention consists in the improved construction of said clamps whichwillbe hereinafter fully described, and particularly pointed out-in theclaim.

Referring to the drawings, Figure 1 is a perspective view of one of myimproved roofingclamps. Fig. 2 isa longitudinal sectional view Fig. 3 isa horizontal sectional View on the line as x in Fig. 2; and Fig. 4 is avertical sectional view, illustrating the device in position foroperation.

The same letters refer to the same parts in 0 all the figures.

5 B, of rubber, leather, or other material which shall be sufficientlyelastic and pliable to enable it to be pressed against the roofing,tiles, slates, or shingles with sufficient force to prevent the devicefrom slipping, and yet without 4o injury to the said roofing material.

C is a n-shaped clamp-frame, to one end of which is swiveled the plate Aby a plate or washer, D, upon the outer side of the said plate A, theother end of the clamp-frame C being provided with athumb-screw, E, tothe innor end of which is swiveled awasher, F, having aprotecting-cushion, G, which may be formed of rubber or other elasticmaterial. The outer side of the plate A is provided near its ends withholes or recesses H H, surrounded by metallic re-enforcing plates orwashers I I.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of my invention will bereadily understood.

To adjust the device in position for operation, the binding-clamp frameis made to straddle the edge of the gable end of the building, andtheclamping-plate A and tighteningscrew E are adjusted against the roofingon opposite sides of said edge. By tightening the said screw the devicewill then be secured firmly in position without danger of injuringtheroofing material. The gutter-hooks, which serve to support the stagingor scaffolding, may now be adjusted in the recesses H in the outer sideof plate A, and they will beheld and supported securely without dangerof slipping or giving way, and without possibility of injury to theroofing, no matter of what material the latter may be composed.

I am aware of the patent to Silver and Fawcett, No. 150,900, May 12,1874, and I claim nothing therein shown.

I claim as my invention and desire to secure by Letters Patent of theUnited States- As an improvement in roofing-clamps, the combination of abinding-plate having a cushion or protectingplate on its inner side, andprovided on its outer side with metal-bound recesses, of a clampswiveled centrally to the outer side of said plate, and having atightening-screw provided at the end facingthe cushioned side of thebinding-plate with a swiveled washer, likewise covered with an elasticcushion, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
